A typical Photinus is a "lightning-bug firefly" (as opposed to the so-called "glowworm firefly") because it emits light in its winged stage. Both male and female adults produce mating signals with an abdominal light organ or "lantern". Members of Photinus are called "rover fireflies" because typically males fly about singly, not in groups ...
While these bugs aren’t bioluminescent, they are often mistaken for fireflies, the most famous light-emitting insects! Soldier beetles are known for their heads mimicking a firefly’s colors.
They are soft-bodied beetles commonly called fireflies, lightning bugs, or glowworms for their conspicuous production of light, mainly during twilight, to attract mates. [5] The type species is Lampyris noctiluca , the common glow-worm of Europe.
Photinus pyralis, also known by the common names the common eastern firefly [3] or big dipper firefly, [4] and sometimes called a "lightning bug", [5] is a species of flying beetle. An organ on its abdomen is responsible for its light production. [ 6 ]
Most light we know produces heat, but bioluminescence does not, making it a ‘cold light’. That means less than 20% of the light produced via bioluminescence generates thermal radiation (heat).
The term comes from the Greek γυνή (gynē) 'female', ἀνήρ (anēr) 'male', and μορφή (morphē) 'form', and is used mainly in the field of entomology. Gynandromorphism is most frequently recognized in organisms that have strong sexual dimorphism such as certain butterflies, spiders, and birds, but has been recognized in numerous ...

Adult male P. macdermotti fireflies fly 0.3–1.2 m (1–4 ft) off the ground and flash to attract the attention of females. Their flash pattern consists of two quick pulses of light, with each pulse approximately 0.25 seconds in length, with a period of 2 seconds of darkness before the next set of 2 pulses at 70 °F (21.1 °C).
